As Peterson recovers from another surgery, Vikings star ready to be more of a receiver

For the third straight offseason, Adrian Peterson is recovering from surgery. The Minnesota star has started the final year of his 20s.

This is point in his career where so many NFL running backs, even the elite, have started to drop off. The wear and tear on their bodies can be too much to overcome.

Peterson is as proud as they come, so after taking part in minicamp this week with the Vikings he wasn't ready to concede any kind of decrease in production. But he has embraced a solution to stemming the tide of aging: catching the ball out of the backfield more, and thus carrying it a little less.
